It's a professional tool - in other words, it's the kind of thing you carry to a job because you'll be paid for doing so. In my opinion it's far too heavy for everyday, carry-about use.

Should a Ferrari road car be driven by formula 1 drivers only?

Sorry - that's not what I meant! I meant that professionals will tolerate the weight because they're being paid to do so!

But.. I do question your suggestion that the 70-200L is a Ferrari! It's a very good quality zoom, for sure, and it's remarkable because it's as good as many primes, but there are also many primes in that range which are better lenses. In some folks' eyes, the zoom has a legendary, holy-grail-like status and they believe that EVERYONE should aspire to own one, but given its weight and bulk I'd argue that it's a specialist tool for professionals who have to work fast in tight, unpredictable spaces. I used to own one, and I hope I never have to carry one ever again.
